Regional Rep

I had a little more drone/ boom when my miltek was resinated. I bought the un resinated section and the noise is strangely more refined now and much easier to live with,
The only time it even seems noisey ( not realy but if your being picky ) is when on tickover from cold goes quiet after about 2 min

Family car... 2001 RS4.

I ask questions because i change my mind so much. If i ask questions you have already covered... just leave it be?

The car is R-Tech mapped to 280bhp and drives very nicely and is quite a peaceful place to be when driving at any speed.

Q1) Would replacing the sports cat with a de-cat offer anything performance wise?

Q2) I'm thinking about fitting a Relentless/XS Power manifold in the near future, do these alter the exhaust noise a fair bit? Have only seen one video on youtube which wasn't that great.

Sport cat / decat performance gains are subjective. Sounds would be more noticeable.

Xs power manifold creates far more noise from the engine bay but in a very good way. When mapped, torque and bhp are greatly improved as the engine is far more free flowing. It's an pain to fit but immense. throttle response is also noticeably better.

You can pick up the version 2 from Sam Bryant, on here, for about £197. You won't regret it.

I had an xs power mani and down pipe fitted onto standard exhaust and it didn't make much more noise at all... Iv since fitted a single box power flow system and it sounds ridiculous outside, but in the cabin it's fine, even on the motorway.

I'm really suprised at that but you will know better of course. The xs power mani on mine totally changed the car noise. You can really hear the whooshing of the air around the engine bay now.

Perhaps mine was assisted by the stage 3 hybrid that I had installed at the same time but interesting that your experience differs. I wonder if others had the same.
